ASD FieldSpec 4 Wide-Res Field Spectroradiometer

The 3 nm VNIR, 30 nm SWIR spectral resolution of the ASD FieldSpec® 4 Wide-Res field spectroradiometer, is a cost-effective solution for the analysis of any material with broad spectral features. General vegetation analysis and water column studies are common application areas that are associated with broader spectral features. The ASD FieldSpec 4 Wide-Res field spectroradiometer can be utilized for many of the same applications as the Standard-Res model although the characterization of material with sharper spectral features will be less precise. The ASD FieldSpec 4 Wide-Res is not recommended for the analysis of materials and compounds with narrow or sharp geological spectral features in the SWIR range such as alteration mineralogy or atmospheric/gas studies.

Because of its wider optical slit the ASD FieldSpec Wide-Res field spectroradiometer delivers the best signal throughput of any ASD FieldSpec spectroradiometer. High throughput benefits measurements taken in low illumination conditions.

This instrument is available at a significantly lower price point than other ASD FieldSpec 4 models, which makes it an attractive option when budgets are tight.

In addition to being a cost-effective field spectroradiometer, the ASD FieldSpec 4 Wide-Res also functions well as a rugged, field spectrometer for accurate contact reflectance or non-solar stand-off measurements.

Probes and Lighting

Contact Probe

The ASD Contact Probe is designed for contact measurements of solid raw materials such as minerals, grains, other granular materials. Its innovative optical design minimizes measurement errors associated with stray light and allows for measurement of samples through clear and transparent plastic bags.

In addition to the standard contact probe, ASD also offer the Hi-Brite contact probe and the Plant Probe.

All contact probes are available with a ruggedized cable feed and cable, designed for applications that involve extra cold or harsh temperatures. (see image below specifications)

Specifications:

Length10" ( 25.4 cm)
Weight1.5 lbs (.7 kg)
Power requirements12-18 VDC, 6.5 W
Lightsource type/Life (approx.)Halogen bulb/1500 hours
Halogen bulb color temperature2900 K
Spot size10 mm

Muglight

The ASD Muglight is designed for analysis of raw materials requiring reflectance and absorbance measurements. It can measure samples through glass vials, or using the ASD sampling tray adapter. It's unique and innovative design minimizes measurement errors associated with stray light and specular reflected components.

For users requiring higher intensity illumination, ASD also offers the Hi-Brite Muglight.

Muglight specifications:

Size5.5” x 3.7” (14cm x 9.4cm)
Weight2.91 lbs (1.3 kg)
Power requirementsInput power 5.5 W, bulb 4 W
Light source (type/life) approx.Tungsten Quartz Halogen b/1500rs
Bulb color temp2900 K
Spot size12 mm

Turntable

When your application requires analysis of irregularly shaped or non-homogeneous samples, the ASD Turntable is ideal for obtaining a highly accurate average. Especially useful for instrument owners in the grain, agriculture, pulp and paper, food, plastics and mining industries.

The Turntable offers:

  • 53.2 mm sampling spot size
  • Rotates at 22 RPM
  • Fits up to a 150mm sample dish
  • Compact (8"x11"x11" or 20.32 cm x 27.94 cm x 27.94 cm) footprint.

The Turntable comes standard with a 4000 hour halogen light source and one standard 150 mm x 15 mm Petri dish.

Plant Probe

The same great design and functionality as ASD's standard contact probe with a lower intensity bulb position for non-destructive data collection from live vegetation and other heat-sensitive targets.

The plant probe can be used alone or in combination with a Leaf Clip to protect sensitive plants.

Leaf Clip

ASD's Leaf Clip assembly is designed specifically for use with the Plant Probe to simplify the process of collecting spectra on live vegetation. The unique design includes a gentle trigger lock/release gripping system for holding the target sample in place without removing the leaf from its habitat, or inflicting damage.

Integrating Sphere

Integrating spheres collect reflected light from samples over a full hemisphere. The sphere, by nature of its internal diffuse (lambertian) reflection and integration of the energy, is insensitive to directional reflectance features coming from the sample, and therefore, gives a very repeatable “averaged” response to the reflectance of the sample placed in the beam at the sphere port. Sample placement and incidence beam/collection alignment are less critical to the measurement results because the integrating sphere looks at representative averaged energy from all angles at the same time.

Fiber Optic Illuminator

The Fiber Optic Illuminator is a portable, external light source designed for use with ASD instruments and sampling accessories that do not have a built-in light source.

Technical Specifications

Length   11.43 cm (4.5 inches)
Width   8.255 cm (3.25 inches)
Weight   292 grams (10.3 ounces)

General Accessories

Pistol Grips

ASD offers multiple pistol grip options for superior ease-of-use and adaptability to a variety of environmental and situational elements, when using your FieldSpec® and FieldSpec HandHeld instruments. All pistol grip designs include the quick-connect/disconnect fiber optic cable snap-in feature, pistol grip clip assembly for safely and securely affixing the pistol grip to your waist-belt on the back pack, and many offer a built-in bulls-eye level for added precision.
